Stone crusher refers to the equipment specially used to crush and process large stone into stone. Common stone crushers include jaw crusher, impact crusher, impact crusher (sand making machine), etc. These kinds of crushing equipment are widely used in stone crushing and stone processing, each with its own advantages. Under different production requirements, different crushers can be selected.
Jaw crusher is also called Tiger mouth, because it is a crusher that simulates the movement of two jaws of animals to complete the material crushing operation. This equipment can be regarded as one of the most frequently used equipment in stone crushing, because the large block stone needs to pass through the coarse crushing of jaw crusher first, and its crushing ratio is large, efficiency is high, structure is simple, suitable for crushing the stone with compressive strength below 320MPa, which has great advantages in stone crushing.

The impact crusher appears much later than jawbone, which is the main fine crushing equipment. It is a new crusher designed on the basis of jawbone. Impact crusher can deal with materials with side length of less than 100-500mm, with compressive strength of up to 350Mpa. It has the advantages of large crushing ratio and cubic particles after crushing. It can simplify the crushing process and make three-stage crushing into two-stage or one-stage crushing.

Another impact crusher is generally called sand making machine, which plays an irreplaceable role in all kinds of ore fine crushing equipment. It is an effective, practical and reliable stone crusher at present. The equipment is suitable for artificial sand making of pebble, cobble, limestone, granite, basalt, diabase, andesite and other stones. It has the advantages of shaping function, cubic product and high stacking density. It is an essential equipment for producing machine-made sand.
